Definitions

  • the invention relates to a synchronous endless conveyor on a spinning machine, in particular a ring spinning machine according to the preamble of claim 1 and a spinning machine with such a synchronous endless conveyor
  • a spinning machine in particular a ring spinning machine according to the preamble of claim 1
  • a spinning machine with such a synchronous endless conveyor
  • the sleeve pins are attached directly to the endless conveyor designed as a horizontal conveyor belt.
  • the endless conveyor is generally designed as a steel belt that warps as little as possible, so that the predetermined distances between the sleeve journals, which must exactly match the distances between the spinning positions, remain unchanged even when the machine is operated for a long time.
  • the sleeve journals are arranged half the distance from the spinning positions, in order to be able to accommodate an empty tube and a full tube (cop) of the assigned spinning position at the same time during doffing, it is also possible to use the as Belt-formed endless conveyor only to provide sleeve pins at a distance from the spinning stations, an additional pin then having to be provided at each spinning station in order to temporarily accommodate one of the sleeves to be replaced when changing the sleeves (US Pat. No. 3,905,184).
  • the problem with the aforementioned ring spinning machines is, on the one hand, that the trunnions form an integral part of the endless conveyor, which is necessary because the trunnions in the sleeve changing position of the endless conveyor must be exactly aligned with the individually assigned spinning position. For this reason, the full sleeves (cops) at the end of the last group of spinning positions must be removed from the trunnion and then reloaded, for example, onto trunnion slides (peg trays) of a winding machine. Conversely, the empty tubes, for example supplied by the winding machine, must be placed on the trunnions at the beginning of the first spinning station group by means of special gripping and lifting devices.
  • the peg trays used in the winding machine connected to the ring spinning machine can also be used as empty tube feed means or full tube discharge means, in that these peg trays, which generally consist of a circular disc and a center pin arranged vertically thereon to be displaced in a guide rail running around the ring spinning machine, the diameter, in particular the length of a pin slide, being slightly smaller than the distance between two adjacent spinning positions.
  • the individual pin slides are in contact with one another and are pushed forward by exerting force on one or more pin slides, the thrust force being at least partially transmitted by the direct contact of the pin slides.
  • a conveyor device for such trunnion slides is also known from DE-OS 35 44 560.
  • a disadvantage of the ring spinning machine according to JP-OS 57-161 134 is that the sleeve journals are not exactly in alignment with the spinning positions if a group of journal carriages with empty sleeves on one machine side has been moved in front of the assigned spinning stations. Therefore, before the sleeve change can be made, a rake must be pushed at right angles to the longitudinal axis of the spinning machine between the pin slides in the known ring spinning machine, so that the distances between the adjacent sleeve pins are coordinated exactly with the distances between adjacent spinning positions.
  • a similar sleeve transport device (DE-OS 37 12 027) is used with a reciprocating rail or the like which extends along the spinning positions and which cooperates with pin slides which can be displaced in a guide rail in such a way that these are gradually moved up to the assigned spinning position .
  • the trunnion slides are exactly aligned with the assigned spinning station, they must either have a length exactly equal to the distance between the spinning stations, or there are latch-like pivotable locking elements on the reciprocating rail, which are located exactly at the distance from the spinning stations, so that the locking elements ensure an exact alignment of the trunnion slides with the assigned spinning position even when the trunnion slides are not in contact with each other.
  • a transport device for providing bobbin tubes and for removing spinning bobbins, in particular on a double-sided spinning machine has already been proposed (not prepublished EP-A-0 337 126), which has an endless belt assigned to a drive, on the driving means for the Coil sleeves and spinning coils are arranged.
  • the belt is designed as a flexible steel belt which is guided upright on both machine sides of the spinning machine by means of guides and / or deflection rollers.
  • Carriers for transporting plates running on sliding surfaces can be fastened to the belt, the carriers having receiving surfaces which match the plates and partially enclose them.
  • a driver is in contact with both the preceding and the following plates, so that the relative position of the plates to the spinning positions cannot be selected independently of the dimensions of the drivers in the conveying direction.
  • the aim of the invention is to provide a synchronous endless conveyor on a spinning machine, in particular a ring spinning machine, of the type mentioned at the outset, in which in particular the same trunnion slides used in the subsequent winding machine are also used for feeding and removing the sleeves on the Spinning machine can be used, but in the sleeve change position of the endless conveyor, an exact alignment of the sleeve pin relative to the assigned spinning station should be ensured without the need for expensive, fault-prone and requiring special maintenance mechanical measures such as the introduction of rakes or the arrangement of pivoting pawls .
  • drivers are attached to the endless conveyor in exact positioning, which only have to be held in entraining mechanical engagement with the trunnion slides in order to ensure an exact alignment of the sleeve spigot with the assigned spinning position in the sleeve changing position of the endless conveyor.
  • this intervention occurs automatically when the trunnion slides have been transported to the spinning station.
  • the peg trays that are common in winding machines can also be used for the feed and removal of the sleeves on the ring spinning machine, and an exact alignment of the trunnions with the spinning positions is ensured without this being an exaggerated manufacturing and Maintenance effort must be driven.
  • the attachment of the drivers on the endless conveyor in precise alignment can be done as well as the known direct attachment of the trunnions to the endless conveyor, although the main advantage according to the invention is that the trunnion slides are only introduced into the guide rail at the loading station and brought into engagement with the rotating drivers can be. At the unloading station, the trunnion slides can easily be removed from the drivers, while the precisely positioned drivers remain unchanged on the endless conveyor, which is realized in particular by a vertically arranged steel belt.
  • both debris of the endless conveyor on a single machine side, expediently, according to claim 3, both debris are equipped with drivers and a pin carriage is assigned to each driver.
  • the endless conveyor is guided around two mutually opposite machine sides of one or more spinning station groups, so that full sleeves (cops) can be removed on both sides of the spinning machine and empty sleeves can be transported in in a single operation.
  • the endless conveyor can be suitably moved forwards or backwards at times by half a division of the spinning position.
  • the arrangement of the additional pegs on the driver is particularly advantageous because conventional peg trays can be used as a result.
  • the measure according to claim 7 is provided.
  • the endless conveyor is used according to one embodiment only for advancing, but not for carrying the trunnion slides.
  • the support rail according to claim 8 is preferably provided for carrying the trunnion slide.
  • the mounting rail can also perform the longitudinal guidance of the trunnion according to claim 9.
  • the driver has a pure drive function.
  • the pin carriage is additionally guided by the driver, for example by being in a snap connection with the latter.
  • the drivers hold the trunnion magnetically.
  • the invention is used with particular advantage in combination with a subsequent winder, the peg trays provided in the winder also promote the sleeves on the spinning machine.
  • the pin carriages guided in groups unsynchronized one behind the other in groups are exactly positioned during the transition to the spinning machine by being brought into engagement in a controlled manner with the precisely positioned drivers.
  • the trunnion slides are removed from their exact positioning on the endless conveyor and fed to the normal transport system of the winding machine, which operates in a completely different cycle than the ring spinning machine. There is therefore no timing interface between the ring spinning machine and the winding machine.
  • a buffer path is expediently connected between the spinning machine and the winding machine in order to have slightly different working speeds to consider both machines.
  • a predetermined supply of full sleeves or empty sleeves, which are arranged on journal slides, is kept available on the buffer sections. If a buffer section is full, the subsequent device can be switched off for a certain period of time. Conversely, by means of suitable switching means, for example operating with light barriers, the supplied device can be temporarily switched off when there are no more storage sleeves on the buffer line.
  • the conveying of the trunnion slides on the buffer sections should be carried out in batches, so that a motor does not have to be switched on and off for each fed trunnion.
  • the full heads can be removed from the sleeve journal on one buffer section.
  • the trunnion slides are also removed from the buffer section, fitted with a new sleeve and then placed on the second buffer section again. Thanks to the monitoring according to the invention, pin slides with full cops are always supplied and the pin slides with empty sleeves are conveyed back into the ring spinning machine.
  • the buffer sections which are to be protected against fiber flight, can also ensure that the full sleeves (cops) are largely protected against fiber flight by rapid transfer into the buffer section.
  • the buffer zone at the exit of the ring spinning machine should have a capacity approximately equal to the number that supplies it Have spinning positions.
  • the gripper-free transfer of the trunnion slides from the spinning machine to the winding machine or the buffer section and vice versa can expediently be carried out according to claim 14.
